Blend broccoli florets and onions in a food processor until all are finely chopped. Add all other ingredients and pulse until combined. Allow to sit for a moment (this lets the coconut flour absorb the liquid).

Meanwhile, heat bacon fat in a large saute pan over medium-high heat.

Dollop spoonfuls of the croquette mixture into the hot fat and allow to cook for a few minutes on each side.

Transfer to a plate lined with paper towels and let drain.

Serve with lemon wedges, a sprinkle of sea salt, freshly cracked black pepper and extra raw onions.
